Issue Loading Old Process / Error Re: sliding_window_validation operator

Hi All-

I'm doing an analysis that is similar to one I did waaaaay back in 2019. I tried loading a process from that old project and am getting the following error:



I've attached a copy of the process.

I see that the Sliding Window Validation (which back then was, I think, in a Time Series extension) is available in the 10.3 version of RM Studio. I'm sure this isn't trivial, but is there a way to "map" the old operator to the new one so that I can load the process?

Any/all workaround solutions would be much appreciated.

Thank you!
